The specific heat of Pb2MgWO6 has been measured in the temperature interval
83-370 K. An anomaly in the specific heat associated with the phase transi
tion at T-0=312.8 K has been discovered. The thermodynamic parameters of th
e structural phase transition Fm3m-Pmcn have been determined. (C) 1999 Amer
